The R911329688 (MSK071D-0450-NN-M2-UP0-RNNN) is a Rexroth Indramat IndraDyn S synchronous servomotor with a D-length, 071 frame size, and a shaft with keyway. It features a winding code of 0450 and utilizes natural convection for cooling. The servomotor has a rated input current of 15.4 A, providing an output torque of 17.5 Nm at 3000 rpm, and delivers a maximum torque of 66 Nm at 6000 rpm with up to 69.3 A. The optical multiturn absolute encoder (EnDat2.1) offers 2048 signal period resolution and is mounted on a rotatable 240° connector. Torque constant is 1.25 Nm/A, voltage constant is 77.1 V/1000 rpm, and winding inductivity is 3.2 mH. Operating noise level is below 70 dB(A). The design is specified for increased concentricity and lacks a holding brake. Internal magnets are used for electromagnetic field generation.

Frequently Asked Questions

What is the practical benefit of a rotatable 240° encoder connector during setup?

The connector allows flexible cable orientation. The adjustment reduces strain on wiring and simplifies integration into tight layouts.

Why is optical encoder technology preferred in precision servo applications?

The encoder delivers high accuracy for position feedback. The design ensures stable performance in applications demanding fine motion control.

How does a multiturn absolute encoder improve operational reliability?

The encoder stores position data even without power. The feature eliminates the need for homing routines after restarts.

What installation considerations arise when using a shaft with keyway?

The keyway provides secure torque transmission. The fit requires precise shaft and hub alignment to prevent wear.

How does increased concentricity design affect mechanical performance?

The construction minimizes runout and vibration. The result is smoother motion which protects bearings and coupled equipment.
